Mounting the frequency converter

Preparing the installation site

The ACS510 should be mounted in a location that meets the requirements of ‘ Preparing for Installation’, page 8.

1. Calibrate the mounting holes. 2.

2. Drill the holes.

Note! Dimensions R3 and R4 have four holes in the top of the module, only two of which need to be used. If possible, try to use the outer two holes (this allows space to remove the fan for maintenance).

NOTE! When replacing an ACS400 with an ACS510. the original mounting holes can be used. The mounting holes are the same for sizes R1 and R2.

For construction sizes R3 and R4. the inside mounting holes on the top of the ACS510 inverter match the mounting holes of the ACS400.

Removing the front panel IP21/ UL 1

1. Remove the control panel, if present. 2.

2. Loosen the fastening screws at the top. 3.

3. Remove the front panel from the top.

IP54/ UL 12

1. If equipped with a guard, remove the screws securing the guard. 2.

2. Move the cover upwards.

3. Loosen the self-tapping screws around the front panel of the inverter. 4.

4. Remove the front panel of the inverter.

The following diagram shows the terminal layout of the module with external dimensions R3.

In principle, the wiring diagrams are similar for all sizes (R1…R6).

The most obvious differences between the R5 and R6 modules are only in the power and ground terminals.

The specific type depends on the mounting surface and structural dimensions:

Environmental and enclosure protection Verify that the installation site meets the requirements for the environment in which it is to be used.

To prevent damage, storage and transport prior to installation must be carried out in accordance with the requirements for storage and transport in the environmental requirements.

See ‘Environmental conditions’ on page 232. Depending on the degree of contamination on site, check that the enclosure protection class is appropriate:

– IP21/ UL 1 Enclosure. The site must be free of floating dust, corrosive gases or liquids, and electrically conductive contaminants such as condensation, charcoal dust, metal particles, etc.

– IP54/ UL 12 enclosure. This enclosure provides protection against airborne dust and light splashes and droplets from all directions.

Make sure that the installation location fulfils the following conditions:

– The frequency converter must be mounted vertically on a smooth, solid surface and comply with the environmental requirements mentioned above.

– The minimum space requirement for the frequency converter is the external dimensions (see ‘External dimensions’ on page 231) plus the ventilation space around the frequency converter.

– The distance between motor and frequency inverter is limited by the maximum motor cable length.

– The installation location must be able to support the weight and noise output of the frequency converter. See ‘Weight’ on page 232.

Preparing for Installation

Lifting the inverter

Lift the inverter by holding the base of the inverter only.

Opening the packing box

1. Open the packing box.

2. Check for damage. If any damage is found, notify the carrier immediately. 3.

3. Check that the contents of the box correspond to the order and the waybill.

Identification of the inverter

To find out which inverter you are installing, refer to the following

– The label on the top of the bar code between the mounting holes.

– Model code on the heat sink – located on the right side of the inverter cover:

Motor Compatibility The motor, inverter and power supply must be compatible:

Tool Requirements The following tools are required to install the ACS510:

– Screwdriver ( to match the fasteners used)

– Wire stripper

– Tape measure

– Drill

– Fasteners: screws or nuts and bolts, four each.

Fasteners: screws or nuts and bolts, four each. 

Synchronisation indicator is on, it means that the two power sources are in synchronised state and parallel operation can be carried out; if the synchronisation indicator is not on, the two power sources are in unsynchronised state, then the circuit breaker will start safety blocking.

At this time, the executive circuit breaker starts safety blocking, and the switch can not execute the closing command in parallel operation mode to ensure the safety of the line.

Alarm Indication: The alarm indicator lights up when abnormal release occurs in the line.

Communication function: After installing communication module, the circuit breaker can have communication function, which can realise remote communication and intelligent control.

Other auxiliary functions

– RTC real-time time

– Key lock function

– Fault locking function

– Event record function

– Alarm function

The system can be fitted with control buttons and mode changeover switches mounted separately on the instrumentation door of the switchboard cabinet.

Manual/automatic/parallel switching is achieved by means of a mode switching button.

The system can be switched automatically according to a predefined procedure or switched to manual mode to exit automatic operation.

In the event of planned maintenance or power failure, manual parallel switching of the power supply is also possible to ensure that important loads are not interrupted by the switching process, thus ensuring continuity of the power supply.

Measurement functions

The Emax 2 Ekip Touch is equipped with a measurement module, which automatically collects and measures the status and parameters of the power supply and displays them visually on the circuit breaker’s LCD screen.

Status indication

The Emax 2 Harness system can also be equipped with a status display function to show the operating status of the system to the user, which is convenient for on-site management.

Voltage Status Indication: The line voltage status of power supply 1/power supply 2 can be indicated by the LEDs. If the power supply voltage status is normal, the indicator light will be always on; if the voltage is abnormal (under/over-voltage), the indicator light will not be on.

Circuit breaker status indication: The status of power supply 1/power supply 2 (normal/abnormal) and the status of CB1/CB2/CB3 actuating circuit breakers (bright – closing; non-bright – opening) are visually displayed in the form of a single-line diagram of the system.

ABB is reinventing the way digital systems are embedded to help customers realise more efficient, safe and stable power system solutions.

Efficient and simple control systems: smart circuit breakers with integrated embedded logic for shorter changeover times.

Simple connectivity: no need for a separate external controller for the circuit breaker, eliminating the need for complex wiring to external protection devices.

Higher Reliability: Ekip release provides a wide range of circuit breaker protection to ensure higher reliability. In the event of a fault, local and remote alarms can be realised, so that faults can be dealt with quickly.

The Emax 2 Harness automatic double power conversion system is equipped with power supply voltage and frequency detection functions.

In addition to the conventional conversion function, it also provides the closed-loop control function (parallel conversion) required by power plants and industries.

This ensures uninterrupted power supply for special applications and brings new solutions for power electronics, semiconductors, airports, petrochemicals, data centres and other industries.

Control Functions

The Emax 2 Harness dual power conversion system comes standard with the Touch intelligent tripper, which not only provides full mains circuit protection, but also supports multiple power sources.

switching functions:

– Automatic switchover – self-recovery – no self-recovery

– Manual changeover (not in parallel)

– Parallel switchover

Emax 2 Harness can be directly through the intelligent off-trigger embedded logic to achieve efficient cooperation between the circuit breaker control, while supporting a variety of control modes, wiring, and so on.

The Emax 2 Harness supports multiple control modes, simple wiring, high reliability, shorter changeover times and intuitive control.

Emax 2 Harness is a high-performance automated power conversion system on the Emax 2 Ekip intelligent protective circuit breakers.

It provides safer and more reliable power switching without the need for additional control equipment, whilst providing circuit protection.
